RIBBON CLASP.

Application filed September 9, 1927. Serial No. 218,448.

This invention pertains to a clasp, more particularly of the kind whichis adapted to be used on ribbons for wrist watches, and similararticles, and the invention seeks to provide a clasp which will securelyfasten the ribbon around the wrist, and which will not be likely tobecome accidentally unfastened.

The article forming the subject-matter of this invention will be readilyunderstood from the accompanying drawing, in which Figure 1 represents,a plan view of the assembled clasp, showing it attached to a ribbon.

Figure 2 is a' section taken on the line 22 of Figure 1, showing themeans of securing the clasp to the ribbon.

Figure 3 is a section taken on the line 3-3 of Figure 1, showing detailsof the form of the clasp. L

Figure 4 is a plan view of the top member.

Figure 5 is a plan view of the bottom member.

Referring to the drawing, it will be seen that the clasp comprises a topmember 1 and a bottom member 2. By bottom member is meant the memberwhich normally is in contact with the wrist of the wearer. It will beseen that one portion 3 of the ribbon is looped through the slot 4 ofthe top member 1, while another portion 3 of the ribbon is threadedthrough the slots 5 and 5 provided in the bottom member 2.

It will be seen from Figures 3, 4 and. 5 that the top member 1 isprovided with recesses nearthe bottom of its flanges, these recessesbeing designated as 6 and 6 It will also be noticed that the bottommember 2 is formed with flanges at its side, and that on these flangesare projections 7 and 7*, which are adapted to fit within the recesses 6and 6 of the member 1, so that the mem ber 1 will be in tight engagementwith the member 2 and at the same time vertical displacement of themember 1 is prevented.

'The member 1 is provided with sufficient springiness to enable it toslip over the projections 7 and 7, and which will also cause the member1 to tightly engage these projections.

It will thus be seen that the invention provides an article of thecharacter set forth, which will be readily manufactured, and which willbe free from liability of accidental unclasping. In order to unclasp thearticle it is necessary to slide the top member from the bottom.

I desire to comprehend within my invention such modifications as may beclearly embraced within my claims and the scope of my invention.

1 Having thus fully described my invention,

.what I claim is new and desire to secure by Letters Patent, is:

1. A ribbon clasp comprising separable top and bottom members, flangeson each member, recesses in the flanges of the top member andprojections on the flanges of the bottom member engaging with the saidrecesses, the said top member being provided with sufficient springinessto tightly engage the bottom member along the lines of the projectionsthereof.

2. A ribbon clasp comprising separable top and bottom members providedwith coacting flanges, the said members being held in engagement byfrictional contact between said flanges, and means integral with thesaid flanges for substantially preventing accidental disengagement ofthe top and bottom parts.

3. A ribbon clasp, comprising separable top and bottom members, a ribbonreceiving slot in the upper member, and a plurality of ribbon receivingslots in the bottom member, flanges on each member, and interlockingmeans on each flange to hold the members in engagement with each other.

4. A ribbon clasp, comprising separable top and bottom members, means inthe top member for engaging a ribbon, a plurality of means in the bottom-member for engaging a. ribbon, a flange on the top member having arecess therein, a projection on the bottom member adapted to engage saidrecess and to lock the top member and the bottom member in engagementwith each other.

5. A ribbon clasp, comprising separable top and bottom members, means inthe top member for engaging a ribbon, a plurality of means in thebottommember for engaging a ribbon, flanges on the top member, eachflange having a recess therein, projections on the bottom member adaptedto engage. said recesses and to lock the top member and the bottommember in engagement with each other.

In testimony whereof I afiix my signature.-
